Title: Improvements in the Casting of Solid and Hollow Circular Metal Bodies.
Inventor: MICHAILOFF SSEMON
Filed: 1901-02-25
Granted: 1901-07-06
Abstract: 4037. Michailoff, S. Feb. 25. Castings; moulding.-A permanent mould for pipes and other cylindrical bodies, constructed so as to produce castings without fins at the joints, is mounted on trunnions a in the centre of its length. The destructible core is withdrawn as soon as the metal has solidified, the interior of the pipe is brushed, and air is admitted to chill it. The pipe is withdrawn while still hot, and may be coated with tar without re-heating. The flask is made in two parts D and E with a longitudinal joint. Longitudinal bars G with retaining-pins g are secured to its inner surface, and the moulding- material is applied to it in two or more layers and dried after each application. When three layers are used, the first layer comprises non-greasy clay and tine-chopped straw mixed with water to a stiff paste. The second layer comprises refractory clay, sand, and horse dung in about equal proportions mixed with water and boiled oil to a plastic mass. The third layer is only 3 or 4 mm. thick, and is of a sticky material comprising 40 per cent. of terra-cotta powder, 15 per cent. of burnt crucible graphite, 10 per cent. of fatty clay, 15 per cent. of washed river sand, 5 per cent. of charcoal, 15 per cent. of cow dung, with water and boiled oil in the proportion of 3 to 1. The surface of the mould is struck up by a mould board K, but a small dovetailed recess h is left at the joint, which is filled with clay and smoothed off after the mould is put together for each casting. The mould is supported in the horizontal position by swing brackets d, and baked by a fire in the casting-pit A, which is closed by the doors V. The core is supported by the end plates O, P, and plastic clay is placed between the mould and core at the ends to make a tight joint.

Granted: 1904-02-11
Abstract: 9284. Grimshaw, A. L., Woodyer, H. S., and Woodyer, W. E. April 24. Advertising.-A circular disc is composed of sections a, Fig. 4, which are rotated so as to bring each face either to the front or normal to the plane of the disc. Advertisements are mounted on both sides of the sections and also on a back screen p. Each section is secured to a radial shaft a', having a pinion a<2> thereon gearing with a toothed wheel d, fixed to a sleeve d<1>, rotated by means of a lever d' and a connecting-rod f. The latter passes through a hole in a plate d<3>, slidably mounted in the lever d<2>, and is attached at its other extremity to a wheel g, rotated by a cord from an electromotor. Stops g<3>, g<4> on the connecting-rod move the lever d' to and fro, thereby presenting to view one or other face of each section, a projection a<3> at the corner of which limits the reciprocating movement. To prevent accidental displacement of the sections when free, an arched brake spring k presses upon a projection k<1> on the lever d<2>. In a modification, Fig. 6, suitable for large discs exposed to wind pressure, the said lever is kept in position by a stop block m normally propelled outwards by a spring m<1>. The stops g<3>, g<4> are provided with cams n, which, at the proper instant, force back the block m and allow the lever to pass. Instead of employing the wheels a', the sections may be operated by forked levers a<5> Fig. 8, acting upon bent springs a<6> secured to and rocking with the sleeve d<1>; fixed cam-surfaces b<1> prevent undue displacement of the sections. The sections may be rotated continuously in the same direction. The disc is illuminated from the front by electric or other lamps arranged round the periphery or at the centre, with or without the use of a convex reflector. The rear screen p may be transparent or translucent and may be illuminated from behind or by front reflection, and when the said screen is not required for displaying advertisements, the sections of the disc are made conical instead of flat. In the Provisional Specification, it is stated that when the apparatus is lit by gas, switches or taps are arranged to cut off the light from the front of the disc when the rear screen is illuminated, thus preventing the formation of shadows on the latter.
